Hi!

I would like to ask the following questions  on separation problem:
1) what is the difference between IL separation and post separation?
2) what causes the occurrence of such kind of defect?
3) how can we prevent this type of problem from occurring?
4) at what layer does this problem usually occur?
5) how can you distiguish separation from resin smear?


thank you very much for any information which you could provide.
